I Clalm.

My invention relates to receptacles, and more particularly to those ofthe cardboard type such as are used as containers for breakfast cereals,soap chips and powders, etc.

One object of my invention is the provision of a packaging containerthat can be produced at no greater cost than various conventional formsof containers. and which will nevertheless possessadvantages -over theprior forms, in the way of conveniently dispensing the contents and moreeffective sealing against entrance of dust or accidental spilling afterthe package has been broken for use.

Another object of my invention is to provide an improved arrangement ofpouring spout and cover, for containers of this character.

Still another object of my invention is to provide an improved manner ofdetachably connecting the free edge of a hinged cover flap to the bodyof the receptacle.

As shown in the accompanying drawing- Figure 1 shows a blank form fromwhich the receptacle may be formed; Figure 2 is a. perspective view ofthe completed receptacle; Figure 3 shows the manner in which thecontents can be dispensed from the receptacle; Figure 4 shows themannerin which the receptacle is reclosed after a portion of itscontents have been removed, and Figure 5 is a view of the upper end ofthe box of Figure 4, with the cloture flap broken away.

As shown in Figure 1, the blank has a front wall portion 5, a back wallportion 6, side wall portions 1 and 8, and a closure flap 9. The blankis shaped to rectangular form by bending the side walls 'l and 8forwardly and then bending the wall 5 into the position shown in Figure2 with its flap I0 glued against the inner surface of the side wall 1.End flaps II, I2, I3, and Il are formed by slitting the blank at I5, I6,and I1, a weakened line being provided at I8 across the blank and otherfold lines being similarly indicated by dash lines. These lower endflaps can then be folded to close such end, and glued into place. asindicated in Figure 2, though this folding operation ordinarily will nottake place until after the container has been filled, and u'ntil afterthe opposite end thereof has been closed.

The closure flap 9 is joined to the rear wall 6 at a weakened fold line20, and has a pair of wings 2| that have tear-off connection theretoalong lines 22 of partial perforation. The full AI and 8 and they may 5,as shown in Figure 2. with the wings 2| lying y ilatwise againstthelnner faces of the side walls of glue.

In some instances the box will be illled after the closure i'iap hasbeen tucked in as above stated, whereupon a closed bag 2B lled with thematerial to be packaged will be inserted from the other end, just beforeclosing and gluing the flap elements |||2|8|4. The entire box, whenpacked may be provided with a temporary thin paper wrapper, as iscommon.

The upper end of the box can conveniently be closed by bending thetongue 28 and the portions 3| ilatwise against the forward face of 9 andthe `wings 2| folded in against 3| and 8, whereupon the flap 9 is foldedinto the closed position (Figure 2). f lRelease of these elements 2| and8| at this time .allows them to spring to their normal positions.

The customer, upon receiving the package, will pull out the closure flapto the position shown in Figure 3 at which time the wings 2| will betorn on the nap at 22 and separated from the side walls 'l and 8, andthen taken out or allowed to fall down in the box.

'I'he top of the bag25 will be torn off and discarded-where a bag isused. Thereupon one of the sidewalls will be flexed outwardly as shownin the lower portion of'Figure 3 to serve as a pouring spout. The sidewalls are scored or otherwise weakened on lines 26, the ap Il beingsimilarly scored at 2l because it partially overlies one of the scoredlines 26.

Upon reclosing the carton after some of its contents have been removedthe` upper portions of the side walls are pushed inwardly a considerabledistance as indicated in Figures 4 and 5, this inward deflection beingfacilitated by reason of the scored lines 26. 'I'he ap 9 is then broughtforwardly over the upper edges of the side walls l and 8 and the frontwall 5. Its free edge is bent down and its tongue 28 inserted into aslit 29 in the front wall 8, as in Fig. 4. Slits 30 permit the tongue 28to be inserted through the slit 29, and the adjacent flap portions 8| tolie against the outer face of the wall 5. Since lines 23 indicate cutsor lines of separation between the wings and the side walls 1 and 8. Atthe time of packing the closure ilap 9 will have its outer free edgetucked in behind the front wall there is some inherent resiliency in thecardboard, the parts 28 and 3| will have some gripping and frictionalengagement with the front wall, to hold the closure ap 9 in place.

It will be seen that the closure flap will hold the upper portions ofthe side walls in their inwardly deflected positions and also maintainthe upper edges of the front and rear walls closer be held thereto vbyspots together, thus forming in eifect a peaked roof eiIect. Where thebox body is of fairly heavy material, a score line can be provided at l2to facilitate bending of the back wail to the form .shown in Fig. 4.

Because the upper portions of the side walls 1 and 8 are held tucked inas in Fig. 4 and the closure nap can be brought into overlying relationthereto and to the front wall, there is a better seal against the entryof dust than is usually possible in the case of boxes which are placedback on a shelf after a portion of their contents have been taken out.

When it is again desired to remove some of the contents the flap 9 willordinarily be lifted and one of the side walls pulled out slightlyl atits upper end, as in Fig. 3. In the case of ne materials it may not benecessary to raise'the flap 8 but to simply pull out the upper end o!one of the side walls, and thereafter push. it back 2g wall.

into the box.
